application filed Sept. 11, 1916, Serial No. I

In my companion application there is described and illustrated arefrigeratory apparatus that can be advantageously used for household-purposes, as the apparatusis very compact. Contributing. to .thiscompactness is a heat absorbing device of novel construction, in so muchthat it provides an extensive circulation for a liquid that can bereadily gasified by absorbing heat.

The primary object of the present invention is therefore to'provide aheat absorbing apparatus or device that will afford extensive sinuous ortortuous passages for a liquid, as ammonia, that may be gasified, in assmall a space as ossible, and this is accomplished by provi cling agroup or battery of parallel communicating heads, having a series ofopposed parallel inner and outer conduits which .willcontinually; con:duct a liquid against surfaces capable of absorbing heat and eventuallyconvert the liquid into a gas.

A further object of my invention is to provide a heat absorbing unitcapable of 40 being readily associated with other units of a similarcharacter, and each unit is composed of parts that are simple inconstruction, durable, inexpensive to manufacture, easy to assemble, andhighly efficient for the purposes for which they are intended.

The above and other objects are attained by a mechanical constructionthat will be hereinafter specifically described and then claimed, andreference will now be had to the drawings, wherein- Figure 1 is alongitudinal sectional view of a heat absorbing unit, partly inelevation;

Fig. 2 is an end view of a group or battery of units connected toprovide an extensive circulating system.

Specification of Letters Patent. Patented Nov. 13, 1917. Applicationfiled September 11,191 Serial No. 119345. i I

In Fig. 2 the heat absorbing units are erally designated A. B. C. D andE, said unitsbeing identical 'in construction. The unlt A is. adapted toreceive a supply of liquidQsuch as ammonia, from a suitable supply pipe1, this pipe being connected to thetop of the unit and another pipe 2leading from the bottom of the unit to the bottom of the unit E.Theupper ends of the heat absorbing units E and D are connected by apipe 3; the upper ends of the units B.

and C are connected by a-pipe l;the lower ends of the units C and .Dconnected by a pipe 5,. and the lowerend of the heat absorbing unit Dprovided with asuitablefoutlet pipet. The pipe 2 may be olfset toprovid;clearance for the pipe 6, as indicated at Considering each unit indetail, reference will now be had to Fig. l showing a distributingv head8 .having opposite. sides.

thereof provided with alining recesses 9 and establishing communicationbetween the recesses in one face. of the head and the recesses in theother face of the head are openings 10, said openings being ofa less.diameter than the recesses 9. Mounted in the openings 10 and protrudingfrom the faces ofthe distributing head 9 are inner conduits 11 disposedin parallelism with the outer ends thereof open. p

Mounted in the recesses 9fandinclosing the inner conduits 11 are outerconduits 12 and .13, the conduits 12, being disposed in parallelism fromone face of the distributing head 8 and the outer conduits 13 inparallelism at the opposite side of the head. The inner and outerconduits 11 and 12 are tubular and with the outer ends of the conduits12 closed and in proximity to the outer open ends of the inner conduits11, a liquid passing through the outer conduits 12 may enter the innerconduits 11 or vice versa. In either instance, the liquid passingbetween the inner and outer conduits provides a thin film or body ofliquid that may readily absorb heat from the walls of the outer conduits12 and in so doing be quickly gasified.

The lower face of the distributing head 8, intermediate the endsthereof, has an opening 14 for a pipe connection and the opening 14communicates with the lowermost outer conduit 13. The upper face of thedistributing head 8 has an opening 15, intermediate the ends thereof,for a pipe con nection and said opening communicates with the uppermostouterconduit 12. The remaining outer conduits I2 communicate with theother outer conduits 13 by angularly disposed ports 16 formed in thedistributing head 8 and establishing communication, be tween the innerends of the outer conduits 12 and the inner ends of the outer conduits13, thereby providing a sinuous or tortuous passage for liquid from oneface of the distributing head 8 to the-other face thereof.

It is apparent that the inner and outer conduits may be made of suchlength as to provide an expensive passage for liquid and consideringthat the unit orrbattery of units is submerged in brine or a similaragent, that there will be a large area to which the ammonia on enteringthe distributing head and the conduits thereof will be exposed to absorbheat and before leaving the distributing head be thoroughly gasifi'ed.The heat absorbing apparatus has been herein specifically referred tofor gasifying ammonia in connection with refrigeratory systems, but itis to be understood that the device may be used for gasifying liquidsother than ammonia and that it may also be used for the distillation ofliquid. Therefore, my invention is susceptible to such variations andmodifications which will adapt the device to various uses.

What I claim is l. A device of the-type described, composed ofcommunicating heat absorbing Gwies of this patent may be obtained forfive cents each, by addressing the Commissioner of Patents,

duits, and an opening communicating with uppermost outer conduits.

2. A heat absorbing unit comprising a distributing head, inner conduitsextending through said head, and outer communicat ing conduits carriedby said head and inclosing and communicating with said inner conduits.

3. A heat absorbing unit comprising a distributing head, parallellongitudinally alining outer conduits extending from opposite faces ofsaid head, and inner conduits mounted in said head and extending intosaid outer conduits.

l. A heat absorbing unit comprising a distributing head, parallel outerconduits extending from opposite faces of said head, said head havingports therein establishing communication between the outer conduits onone face thereof and the outer conduits on the opposite face of saidhead, and inner conduits mounted in said head and extending into saidouter conduits.

5. A heat absorbing unit comprising a dis tributing head, parallel innerconduits extending through said head and having the ends thereof open,and outer conduits inclosing the ends of said inner conduits, said outerconduits having the outer closed ends thereof in proximity to the outeropen ends of said inner conduits, and said head having ports thereinestablishing communication between the inner ends of said outer conduitsand inlet and outlet openings in said head.

In testimony whereof I aflix my signature in presence of two witnesses.
